A method to prepare nonwoven webs which have good MD and CD strength, and are water disposable is provided. The method includes hydroentangling an airlaid web of no less than 50% by weight of natural cellulose fibers having a fiber length of no more than 3.5 mm and no more than 50 % by weight staple fibers having a fiber length of no less than 8.0 mm. The airlaid web is not laid on a precursor web and no adhesive, binder or thermal bonding fibers are utilized. The airlayering and hydroentangling are conducted in a continuous operation. Products may be obtained according to the method of this invention that meet municipal guidelines for flushability.
摘要:
The present invention relates to a method of producing a fine fiber, the method comprising the steps of: treating a cellulose raw material with an enzyme; and fibrillating the treated cellulose raw material; the step of treating with the enzyme comprising treating under a condition where at least a ratio of EG activity to CBHI activity is 0.06 or greater. Preferably, the cellulose raw material is selected from plant fibers. The present invention can provide a method of producing a fine fiber that efficiently produces a fine fiber from a cellulose raw material at low cost and with a low environmental burden; a fine fiber; and a non-woven fabric.

Flame resistant fabrics are formed by warp and fill yarns having different fiber contents. The fabrics are constructed, for example, by selection of a suitable weaving pattern, such that the body side of the fabric and the face side of the fabric have different properties. The fabrics described herein can be printable and dyeable on both sides of the fabric and are suitable for use in military and industrial garments. Methods of forming flame resistant fabrics, and methods for forming garments from the fabrics, are also described.

The threads, strands, or cords of said lap or said mesh are parallel in at least one direction and are each simultaneously composed of mineral fibers having low elongation (high modulus of elongation under stress) and an elongation at break value of 2 to 5%, and polymer fibers and/or natural origin fibers having a modulus of elongation under stress lower than that of the mineral fibers and an elongation at break value significantly higher than that of said mineral fibers, of 10 to 20%.

Dyed fabric compositions have now been discovered that often have a balanced combination of desirable properties. The dyed fabric comprises one or more elastic fibers wherein the elastic fibers comprise the reaction product of at least one ethylene olefin block polymer and at least one crosslinking agent. Often the fabrics are characterized by a color change of greater than or equal to about 3.0 according to AATCC evaluation after a first wash by AATCC61-2003-2A.
摘要:
There is provided a process for production of fabrics that vary in glossiness depending on the viewing angle without loss of soft hand quality and that have a highly aesthetic appearance, as well as fabrics and fiber products obtained by the process. The process for production of fabrics of the invention is characterized by pressurized heat treatment of a fabric containing an organic fiber A with a monofilament diameter of 50-1500 nm, and having a woven or knitted texture. The highly aesthetic fabric of the invention also contains an organic fiber B with a monofilament diameter larger than 1500 nm, as an additional fiber.
摘要:
A novel method of weaving is described wherein warp and weft are supplied in the form of tapes, and not yarns. The method, which is preferably carried out in vertical format, essentially includes feeding positively flat tensionless warp for shedding and taking-up; selecting, feeding positively and inserting weft tapes of different widths and thickness by gripping in its fore end in flat condition; depositing inserted weft at fabric-fell in a flat condition without beating-up; and taking-up the woven material that comprises either same or different widths of flat wefts. The warps and wefts, preferably of partially stabilized type of fibrous tapes, can be overfed in a tensionless, positive and controlled manner when required to make the fibres of constituent fibrous tapes occur non-linearly in the form of wave/texture during weaving. Extra warps and wefts can be also fed in tandem whereby the warps and wefts become composed of two or more unconnected, mutually slipping, flat tapes in a stacked arrangement. These doubled warp and wefts function effectively as a unit warp and weft during weaving and in the fabric. The method also makes possible to produce other materials such as those with slant weft tapes in relation to warp, having a shape within the body of the fabric and warp and weft tapes of shaped edges. A variety of fibrous and non-fibrous materials are equally well processed.
摘要:
Novel woven materials, producible by a new weaving method, are described that comprise single or doubled warps and wefts in the form of tapes that are preferably partially stabilized type of fibrous tape. These fibres are caused to occur in a non-linear arrangement during the weaving process. The non-linear fibres can be subsequently straightened by pulling the tape longitudinally. The doubled warps and wefts comprise disconnected tapes. Such separateness of constituent tapes of doubled warp and weft tapes enables them to be slid/slipped relative to each other by pulling longitudinally and laterally without causing any alteration in the woven structure. These novel fabrics solve the problem of uneven fibre distribution and orientation arising from crumples/wrinkles due to compression and stretches due to extension, at the inner and outer sides respectively, when tape- woven fabrics are curved into shapes. Further, by using doubled warps and wefts fabrics with relatively flat/planar sections and thicker/raised wide rib sections can be also created that resemble a bit like a profiled material in its cross-section. Other fabrics like those comprising slant/oblique weft tapes, shaped warp and weft tapes, formed shape within its body are also producible.
